Leibniz’s Principle: Leibniz's law, or identity principle, states that if in the complete descriptions of objects exactly the same properties are attributed, we are concerned with the same object. In the case of identity, it is never a matter of two or more objects, but one, for which there are often different descriptions with different choice of words. Not every description is complete, so identity does not follow from each indistinguishability. See also identity, intensions, extensions, distinguishability, indistinguishability._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
